# ShopfloorConnect Installer Improvements

**Date**: 2025-10-10
**Version**: 1.1

## Changes Made

### 1. Fixed Output Directory Path (Line 16)

**Before**:
```pascal
OutputDir=C:\Users\570005354\Downloads\Output
```

**After**:
```pascal
OutputDir=.\Output
```

**Reason**: The hardcoded user path would fail when building on different machines. Using a relative path `.\Output` creates the output directory next to the `.iss` script file.

---

### 2. Added Comprehensive Error Handling

**Before**:
- No error checking on `Exec()` calls
- No validation of result codes
- Installation continued even if steps failed
- No feedback if something went wrong

**After**:
- ✅ Checks both `Exec()` return value AND `ResultCode`
- ✅ Shows detailed error messages with error codes
- ✅ Exits installation on failure (prevents cascading errors)
- ✅ Provides remediation steps in error messages
- ✅ Validates that configuration file was created

---

### 3. Fixed Batch File Pause Issue (Line 61)

**Problem**: The `install.bat` file has a `pause` command at the end (line 93), which would hang the installer waiting for user input.

**Solution**: Added `echo. |` to pipe a newline to the batch file, automatically responding to the pause:

```pascal
// Before
Exec('cmd.exe', '/c cd /d "C:\ShopFloorConnect\MachineToolClient_Service" && call install.bat', '', SW_SHOW, ewWaitUntilTerminated, ResultCode);

// After
Exec('cmd.exe', '/c cd /d "C:\ShopFloorConnect\MachineToolClient_Service" && echo. | call install.bat', '', SW_SHOW, ewWaitUntilTerminated, ResultCode);
```

---

### 4. Added Comprehensive Installation Validation (Lines 73-130)

**New Features**: After running installation steps, the installer now performs multiple validation checks:

#### 4a. Verify FIT-MI_Server Folder Created (Lines 73-85)
```pascal
if not DirExists('C:\ShopFloorConnect\FIT-MI_Server') then
begin
  MsgBox('Installation Error: FIT-MI_Server folder not created!' + ...);
  Exit;
end;
```

This checks that the Ant build script successfully created the service folder structure.

#### 4b. Verify Windows Service Registration (Lines 87-106)
```pascal
// Query the Windows service
if not Exec('cmd.exe', '/c sc query SFCMTCService', '', SW_HIDE, ewWaitUntilTerminated, ResultCode) then
begin
  MsgBox('Warning: Unable to query Windows service!' + ...);
  Exit;
end;

if ResultCode <> 0 then
begin
  MsgBox('Service Registration Failed!' + ...);
  Exit;
end;
```

This verifies that the Windows service "SFCMTCService" was actually registered and is queryable.

#### 4c. Verify Configuration File Created (Lines 121-130)
```pascal
if not FileExists('C:\ShopFloorConnect\FIT-MI_Server\webapps\wut\WEB-INF\conf\mi_server.ini') then
begin
  MsgBox('Configuration Error: mi_server.ini not found!' + ...);
  Exit;
end;
```

This ensures the critical configuration file was created and populated.

**Why These Checks Matter**: These validations catch installation failures early and provide specific error messages with remediation steps, preventing the "Installation Complete!" message from showing when installation actually failed.

---

### 5. Enhanced Error Messages and Success Confirmation

All error messages now include:
- Clear description of what failed
- Error codes when available
- Specific file paths involved
- Remediation steps (what to do manually)

**Example Error**:
```
Service Registration Failed!

The Windows service "SFCMTCService" was not created.
Error Code: 1060

The installation may have completed, but the service was not registered.

You may need to manually register the service by running:
C:\ShopFloorConnect\FIT-MI_Server\Tomcat 5.0\bin\SFC_MTC_Tomcat_service.bat install
```

**Enhanced Success Message** (Lines 132-145):
The completion message now includes service details and instructions:
```
Installation Complete!

The ShopfloorConnect MTC Service has been installed and configured.

Windows Service: SFCMTCService (Registered)
Startup Type: Delayed Automatic
Site Configuration: West Jefferson CA-LR
Teamcenter Server: 10.233.113.141
Shop Floor PC FQDN: Auto-detected

Config file: C:\ShopFloorConnect\FIT-MI_Server\webapps\wut\WEB-INF\conf\mi_server.ini

To start the service:
  1. Open Services (services.msc)
  2. Find "SFCMTCService"
  3. Right-click → Start

Or run: sc start SFCMTCService
```

## Testing Recommendations

### Test Case 1: Successful Installation
1. Run installer on clean Windows PC with admin rights
2. Verify all 3 steps execute without errors
3. Confirm success message appears
4. Check that `mi_server.ini` file exists and contains correct settings

### Test Case 2: Missing Admin Rights
1. Run installer without admin rights
2. Should fail at Step 2 (setx /m)
3. Should show error: "Failed to set TCFITDIR environment variable!"

### Test Case 3: Installation Failure Recovery
1. Simulate failure by renaming `install.bat` temporarily
2. Run installer
3. Should fail at Step 3 with error message
4. Should NOT show "Installation Complete!" message
5. Should provide manual remediation steps

### Test Case 4: Configuration File Verification
1. Run installer normally
2. If `install.bat` fails silently (doesn't create FIT-MI_Server folder)
3. Should catch this at Step 5 (file validation)
4. Should show: "Configuration file not found"

## Compatibility Notes

- **Inno Setup Version**: Requires Inno Setup 6 or later
- **Windows**: Windows 7 and later (x64)
- **Admin Rights**: Required for `setx /m` and Windows service installation
- **Dependencies**: None (all files included in installer)

---

## Known Limitations

1. **Site-Specific**: Hardcoded for West Jefferson CA-LR
   - To change sites, must edit line 59 and rebuild installer
   - Future: Could add wizard page for site selection

2. **Single Installation Path**: Fixed to `C:\ShopFloorConnect`
   - Cannot be changed by user during installation
   - This is intentional (service expects this path)

3. **No Rollback**: If installation fails mid-way
   - Files remain in C:\ShopFloorConnect
   - Environment variable may be set
   - User must manually clean up or re-run installer

---

## Files Modified

- `ShopfloorConnect.iss` - Main installer script (improved error handling)
- `README.md` - Enhanced troubleshooting section
- `IMPROVEMENTS.md` - This file (new)

## Files Unchanged

- `Run_ShopfloorConnect_Installer.bat` - Batch launcher (still valid)
- `ShopFloorConnect/` - Source files (no changes needed)
- `*.bmp`, `*.ico` - Image assets (no changes)

---

## Next Steps (Optional Enhancements)

1. **Add Site Selection Wizard Page**
   - Let user choose between West Jeff / Rotating Parts / Wilmington
   - Eliminates need to rebuild installer for different sites

2. **Add Installation Logging**
   - Create `C:\ShopFloorConnect\install.log` with timestamps
   - Log each step and result code
   - Helpful for troubleshooting

3. **Add Pre-Installation Checks**
   - Verify Windows version
   - Check available disk space (needs ~200MB)
   - Detect if service already installed

4. **Add Uninstaller Enhancements**
   - Stop service before uninstalling
   - Remove environment variable
   - Prompt to keep configuration files
